Because I saw some folks thinking this was a website of a research project, a little disclaimer: it is not. It’s just a website of a couple of antiprostitution activists (the creepy extreme ones imho) trying to pass off their views as science.
You’ll find similar websites by US conservative christian ‘researchers’ showcasing the ‘harm of homosexuality’, the ‘threat’ of trans women or whatever anti-lgbti political goal is en vogue that week. You’ll find similar websites ‘proving’ how terrible and violent refugees behave in Europe, building elaborate narratives based on made-up news reports. Don’t forget anyone can publish nonsens on the internet.
That includes me, so don’t take my word for it – always be mindful of your sources. What are your source’s source? Do the research methods measure what the writer claims they measure? Are we talking about things we know or things we guess? Are you using first-hand or second-hand info? Is an ‘academic artice’ really published in a legitimate academic journal via a process of peer-review? Etc etc etc
